With the advancements in electronic and manufacturing technologies, medical devices have become smarter, miniaturized, and packed with more functionalities, such as the capability to communicate with smart phones. In addition, in order to have all-around care for the patients, many of these devices are designed to be portable or even wearable on the patients. In order to support these design needs, the energy demand of these devices become increasingly higher. As a result, medical batteries must be smaller and more powerful to catch up with the growth of these devices.
In this presentation, the latest developments in the lithium ion rechargeable batteries will be introduced. We hope that this can be useful for the designers to enhance the performance of future medical devices.
